[QUOTE=indysolar;4048]took hub out, everything looks clean. some of the coil side slats (magnets?) on the edge of the hub are a little pushed out, but no obvious damage to either rotating electric surfaces or coil wires. can i pull it apart to check wires on other side?
i’ll push slats back in, reassemble & put on power supply to test rotation. can’t turn it by hand, but power supply check will be non-controller test.
can i prep the motor magnets / surfaces w/ anything? acetone? def gonna grease all the mechanical surfaces, what about electric surfaces? humidity & water are a ■■■■■ here.
thank you guys.
Don’t worry so much about laminations being out of place. You could do more damage trying to push them back in should you pinch one of the windings with it. Powering up the motor on a dc supply won’t do anything but hold it from turning.
You haven’t answered, can you turn the motor without the controller connected?
You can clean the motor with electronic parts cleaner. Try not to spray the bearings directly. I know there is a high temp clear coat used for car engines. Try an auto part store. A light coat of that should be ok.
